Skin infection due to Mycobacterium marinum in a renal transplant recipient

We report a case of a skin infection due to Mycobacterium marinum in a renal transplant recipient (RTR). The disease resolved completely after four months of treatment with ofloxacin. In RTR the clinical picture is worsened by drug-induced immunosuppression and there is a high risk of systemic involvement, impairment of renal function and rejection of the grafted kidney. The potential nephrotoxicity of some anti-tubercular drugs requires careful monitoring of renal function, so close dermatological surveillance of RTR is a prerequisite for an early diagnosis and treatment of all high-risk lesions.
